F08 - Minimum output-off time:
The minimum time the output will remain off, i.e. the length of time between the last start up and the next
stop. It relieves the discharge pressure and increases the service life of the compressor.
F09 - Refrigeration time (interval between defrosts):
Corresponds to the time in which the refrigeration function will operate via the controller. When this time
is up the controller enters the defrost process.
F10 - Defrost time:
This is the defrost duration time. Within this period, the relay will remain off, and upon finishing, the
controller will go back to the refrigeration state.
F11 - Initial status when turning on the device:
It allows defrosting when controller is turned on.
F12 - Temperature indication locked during defrost:
The real
time temperature indication will only be released at the next refrigeration cycle after it reaches the
“locked” temperature value again, or after 15 minutes in refrigeration (as a safety measure).
F13 - Delay in turning on device:
When the device is switched on its control output will remain disabled, delaying the beginning of the
process. During this time the controller only works as a temperature indicator. The purpose is to avoid
peaks of electric power demand after a power cut when many devices are connected to the mains. To do
this, simply set different times for each device. This delay may be either for the compressor or the
defrost (when the defrost is configured during the startup).
NOTE:
At its end, the count of minimum time of output off is started, if there is any.
F14 - Additional time to the end of the first cycle:
Aimed at increasing the refrigeration time only in the first refrigeration cycle, increasing the efficiency.
F15 - Compressor state with a disconnected or faulty sensor:
If the room sensor is shorted, disconnected or out of range, the compressor will assume the state
configured in this function.
[,,,0]
- Compressor off
[,,,1]
- Compressor on
[,,,2]
- Cycling according to times defined in
[,F16]
and
[,F17]
NOTE:
If the system is in both heating and error mode, the output will be switched off.
F16 - Compressor time on in case of error:
F17 - Compressor time off in case of error:
Sets the minimum time the compressor will remain on/off respectively when the sensor is disconnected
or out of range.
F18 - Digital filter intensity:
This filter has the purpose of simulating thermal mass increase in the sensor, thus increasing its
response time (thermal inertia). The greater the value set in this function, the greater the sensor
response delay will be.
F19 - Time for function lock:
When this function is active, the setpoint and other parameters are protected from undue changes.
When the controller is locked the user can only view the setpoint and parameters. To lock the functions,
see item 8.3.3 - Basic Operations, item Function lock.
F20 - Control functions shutdown:
Allows the output to be switched off for maintenance purposes, see item 8.3.4 - Basic Operations, item
Turning off the control functions.
F21 - Datalogger operating mode:
Indicates how to activate the device that records data in the internal memory:
[,,,0]
- Always off
[,,,1]
- Always on
[,,,2]
- Manual operation
F22 - Time between each sample in the memory:
The time in seconds that the controller takes to record samples of the temperature information and
refrigeration output state.
F23 - Minimum temperature change to force the writing of data:
The temperature difference in relation to the last piece of data written in the datalogger for the data to be
recorded in the memory regardless of the sampling time set in
[,f22]
. To deactivate this function, just
decrement the value until the message
[no,,]
is displayed.
F24 - Output change to force the writing of data:
Indicates whether the change in the control output will force the recording of data in the memory
regardless of the sampling time set in
[,f22]
.
F25 - Overwrite memory?:
This function indicates whether the controller should start writing new data at the beginning of the
datalogger memory when the memory is full. This function prevents the last data calculated by the
equipment from being lost.
F26 - Digital input operating mode:
Aims to program the controller with the type of door sensor used in the installation.
[,,,0]
- Off
[,,,1]
- NC door contact
[,,,2]
- NO door contact
F27 - Address of the instrument in the RS-485 network:
Equipment's network address for communicating with Sitrad software.
Note:
Every single controller within the network must have different address.
This function is aimed at avoiding viewing the room temperature rise due to the defrost cycle. The last
temperature measured in the refrigeration cycle will be locked in the display during the defrost.

Ecase protective cover
It is recommended for the Evolution line, keeps water from entering the back part of the instrument. It
also protects the product when the installation site is washed.
ECASE PROTECTIVE COVER
Extended frame
It allows the installation of Evolution line controllers with sizes 76 x 34 x 77 mm in various situations,
since it does not require precision in the notch of the instrument fitting panel.
The frame integrates two switches of 10 Amperes that may be used to actuate interior light, air curtain,
fan, and others.
